STOVE.

SPECIFICATION forming part of Letters Patent No. 346,939, dated August10, 1886,

(No model.)

To all whom it may concern:

Be it known that I, DAVID M. MURRAY, a

. citizen of the-United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and usefulImprovements in Stoves; and I do hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relatesto improvements in stoves, and it consists of thearrangement of the several parts, as will be fully hereinafter setforth. The objects are to consume the fuel by a downward draft throughthe same, to ef feet a very complete combustion, and to so situate thefire-pot as to prevent any escape of smoke to the external air. I attainthese objects by the mechanism illustrated in the ac:

oompanying drawings, in which Figure 1 is a front elevation of thestove. Fig.2 is a longitudinal section of the same on the line 8. Fig. 3is a horizontal section of the same, on the line Fig. 4 is a horizontalsection of the base,on the line y. Fig. 5 is a topview of the supportingcasting or holder for the grate. Fig. 6 is a top view of the grate.

Like letters designate like parts throughout the several views.

Theform of theslove is shownin Figs. 2 and 4. Projections on the sidesserve as fines, and a top projection serves for the attachment of thepipe.

A represents the external plates of the stove. The front plate, theplate L, and the sides form the radiatingchamber inclosing the fire-pot.These plates are supported on the 1 plate which divides the ash-pit fromthe radiating part of the stove. may be placed mica windows, as shown ato 0, Fig. 1.

B is the top, which has a register in its front plate, to admit the airfor combustion, and the lid 0 is pivoted at the apex, through which thefuel may be supplied to the firepot. Vithin the plate over the ash-pitis held the grate-holder H, which is shown in 'doors in the base.

In the front plate section at Fig. 2, and a top view at Fig. 5. 011 aprojection of this holder rests the grate G, and in a recess of the samerests the the pot E. This fire-pot fills the space above, and the bottomis narrowed to cover the space 00- cupied by the grate. The grate can bemoved longitudinally for the purpose of shaking down the ashes, and forthis purpose the handle G is used. Between plate F and L there is aspace which serves as a flue, and the top of which is closed by thedamper D, which is pivoted in the side plates of the stove. The plate Fis on a line with plate or diaphragm F, and the former fills the spacewithin the base,with the exception of the passages to the sides, asshown at F, Fig. l. On the rear wall is cast a thimble for the pipe M.

AtN N are shown the side flues,that convey the products of combustioninto the space between the rear outer wall and the diaphragm F.

I I are doors opening into the ash-pit, and within which are theordinary circular registers.

Either anthracite or bituminouscoals may be used, and the operation isthus: The kindling and fuel are put into the fire-pot through the topand are ignited through the The register in the top is opened, the airpassing down through the 8 fuel to support combustion, carrying thegases and smoke down to be consumed at and beyond the lower edges of thegrate, the products then passing to the side of the base,

vertical plate, up the side ilues, between the,8 5

back walls, and into the pipe extending to the flue leading to theoutward air. To arrest combustion the damper D is opened, letting theair pass off over the fire-pot through the intermediate line, and passoff as before 0 described. 1

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is
